Dr. Bernd Porr has shared his open-source webpage, BPM Biosignals, with Open Behavior in hopes of providing an educational resource regarding the construction and implementation of bioamplifiers as well as interpretation of biosignals.
“BPM biosignals provides a no-nonsense approach to assembling a two stage bio-amplifier and then using it to measure ECG, EEG, EMG and other biosignals. The page features the list of components, the circuit diagram and video tutorials how to assemble the amplifier and how to use it properly. The main aim of this page is biosignal education, in particular how to to distinguish noise from actual biosignals. One will learn that often noise is “sold” as a biosignal, even in top level publications. With the help of these clips one can critically evaluate such results and make up their own mind.”
